Two simple pendulums of length 0.5 m and 20 m respectively are given small linear displacement in one direction at the same time. They will again be in the phase when the pendulum of shorter length has completed oscillations

When an oscillator completes 100 oscillations its amplitude reduces to 1\3 of its initial value. What will be its amplitude when it completes 200 oscillations?
